STRUCT CFG80211_NAN_CONF(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so this is the struct cfg80211_nan_conf manpage (kernel API manual, section 9) — literally the struct that holds your NAN configuration. that's it, that's the vibe ✨

✨ SYNOPSIS ✨

bestie, here's the whole glow-up, verbatim, do not touch:

struct cfg80211_nan_conf {
    u8 master_pref;
    u8 bands;
    u8 cluster_id[ETH_ALEN];
    u16 scan_period;
    u16 scan_dwell_time;
    u8 discovery_beacon_interval;
    bool enable_dw_notification;
    struct cfg80211_nan_band_config band_cfgs[NUM_NL80211_BANDS];
    const u8 *extra_nan_attrs;
    u16 extra_nan_attrs_len;
    const u8 *vendor_elems;
    u16 vendor_elems_len;
 };

like, every field is right there, no cap 🫶

🎀 MEMBERS 🎀

okay now we go field by field, main character by main character 👑

  • master_pref — the master preference, and it takes a value from 1 – 255. tiny range, big responsibility 💅
  • bands — the operating bands, and this one is a bitmap of enum nl80211_band values. for example, for NL80211_BAND_2GHZ, bit 0 would be set (i.e. BIT(NL80211_BAND_2GHZ)). bit math but make it fashion ✨
  • cluster_id — the cluster ID used for NAN synchronization. it's a MAC address, and it can take a value from 50-6F-9A-01-00-00 to 50-6F-9A-01-FF-FF. so cute, so specific 🎀
  • scan_period — the period (in seconds) between NAN scans. seconds!! not ms, don't get it twisted 🙈
  • scan_dwell_time — the dwell time (in milliseconds) for NAN scans. yes, this one's ms. the units are doing the most on purpose 😭
  • discovery_beacon_interval — the interval (in TUs) for discovery beacons. TUs, bestie, TUs 🦋
  • enable_dw_notification — a flag to enable/disable discovery window notifications. on or off, icon behavior 🔥
  • band_cfgs — an array of band specific configurations, indexed by enum nl80211_band values. one config per band, indexed, obsessed 💜
  • extra_nan_attrs — a pointer to additional NAN attributes. pointer energy 🌸
  • extra_nan_attrs_len — the length of the additional NAN attributes. the pointer's plus-one fr fr 🫶
  • vendor_elems — a pointer to vendor-specific elements. vendor said lemme add something 🍓
  • vendor_elems_len — the length of the vendor-specific elements. and the length said same 💅

🌸 DESCRIPTION 🌸

so, plainly: this struct defines NAN configuration parameters. that's the whole plot. every field above is a knob you get to turn, and this is the package they all live in 💖

more parts coming, stay tuned bestie 🌈
